1.新建项目
建立步骤
新建maven项目无骨架版（我是直接建立的一个模块）
空骨架建立以后，开始继续下一步：
创建包结构：
2.jar的准备
pom.xml
<?xml version="1.0" encoding="UTF-8"?>

把这个复制到pom.xml，出现这个以后，点击，引入项目所需要的依赖。
3.准备静态资源
webapp
jsp/itemList.jsp itemEdit.jsp
（关于静态资源）：
itemEdit.jsp：
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>

4.准备配置文件
位置描述：
controller 层
springmvc.xml 配置包扫描,只扫描controller一个包， 三大组件: 注解驱动 视图解析器
springmvc.xml:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!-- springmvc.xml
配置包扫描,只扫描controller一个包
三大组件: 注解驱动 视图解析器-->
<context:component-scan base-package="com.yanlong.controller"/>
<mvc:annotation-driven />
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp"/>
</bean>
</beans>service 层：
1)applicationContext-service.xml 包扫描service包 2)applicationContext-transaction.xml 配置事务 平台事务管理器注入dataSource 配置一个增强 配置aop 配置切点 切点和增强组合
applicationContext-service.xml：
配置包扫描,只扫描service层
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<!-- applicationContext-service.xml
配置包扫描,只扫描service层-->
<context:component-scan base-package="com.yanlong.service"/>
</beans>applicationContext-transaction.xml：(?)
平台事务管理器
配置通知增强
配置aop(配置切点 配置增强和切点的组合
<?xml version="1.0" encoding="UTF-8"?>

<!-- applicationContext-transaction.xml
平台事务管理器 (注入dataSouce)
配置通知增强 (挂在平台事务管理器)
配置aop(配置切点 配置增强和切点的组合)-->
<!--1.加载外部数据源-->
<bean id="dataSource" xml:base="db.properties"/>
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="add*" isolation="REPEATABLE_READ" propagation="REQUIRED" read-only="false" timeout="-1"/>
</tx:attributes>
</tx:advice>
<aop:config>
<aop:pointcut id="pointcut" expression="execution(* com.yanlong..add*(..))"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="pointcut"/>
</aop:config>
</beans>dao 层
applicationContext-dao.xml
1.加载外部数据源
2.创建连接池
3.配置SqlSessionFactoryBean工厂对象(设置连接池 , 设置加载SqlMapConfig.xml 包扫描别名)
4.编写MapperScannerConfigurar扫描 (扫描mapper包创建代理对象,加载映射文件)
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<!-- applicationContext-dao.xml
1.加载外部数据源
2.创建连接池
3.配置SqlSessionFactoryBean工厂对象(设置连接池 , 设置加载SqlMapConfig.xml 包扫描别名)
4.编写MapperScannerConfigurar扫描 (扫描mapper包创建代理对象,加载映射文件)-->
<context:property-placeholder location="classpath:db.properties"/>
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${jdbc.driver}"/>
<property name="url" value="${jdbc.url}"/>
<property name="username" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
</bean>
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="configLocation" value="classpath:SqlMapConfig.xml"/>
<property name="typeAliasesPackage" value="com.yanlong.pojo"/>
</bean>
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.yanlong.mapper"/>
</bean>
</beans>SqlMapConfig.xml (空的)
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
</configuration>ItemMapper.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="">
</mapper>
其他的配置 :
db.properties 数据库的配置
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/yanlong?characterEncoding=utf-8
jdbc.username=root
jdbc.password=123456log4j.properties 日志配置:
# Global logging configuration
log4j.rootLogger=INFO, stdout
# Console output...
#以下配置输出到控制台
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
#输出的格式
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%nweb.xml
1) 配置监听器加载spring的配置文件
2) 配置DispatcherServlet前端控制器 (加载springmvc.xml文件)
5.maven部署tomcat：
6.测试
启动服务器,如果没有报错.环境搭建完毕.
